Definitions
- the invention relates to an encasing for a door drive adapted to open and/or to close a connected door leaf.
- Door operators namely door drives or door closers, are provided for actuating a door leaf of a door system. With pivotable doors, such door operators are installed most of the time at a top side at a door transom or a wall and are operatively connected to an associated door leaf via an arm assembly. There are door operators configured with an electro-motor or with electro-hydraulics. Such door drives for opening the door are typically activated by a momentary contact switch or a motion-sensor, and they execute both the opening procedure of the door leaf and the mostly time-delayed closing procedure. Furthermore, door operators are known which, for the purpose of controlling an escape route for example, are coupled to a bus of a building. Fully automatic door operators are very common in particular in public buildings, as well as in the infrastructure area of larger building complexes, which have a higher volume of people passing through.
- the door operator has a mounting plate, stationarily affixed to a carrying body, namely a door transom, a wall, a casing, a door leaf or a door frame for example, by a screw-connection or any other known type of connection.
- a mounting plate stationarily affixed to a carrying body, namely a door transom, a wall, a casing, a door leaf or a door frame for example, by a screw-connection or any other known type of connection.
- the mounting plate is installed at the carrying body, the door operator itself is installed on the mounting plate.
- the plate has, for example, pre-fabricated threaded bores or through-openings for screw-connections to firmly connect the door operator to said carrying body via the mounting plate.
- An inventive door operator is adapted to open and to close a connected door leaf. It is furthermore adapted to be stationarily affixed to a carrying body, such as a casing, a transom, a door leaf, or the like.
- the door operator has at least one lateral screen and a covering hood. In the installed condition, the covering hood is configured to be open towards the respective lateral screen. This means the at least one lateral screen, and not the covering hood, forms the frontal termination of the so-formed encasing for the door operator.
- the door operator has fastening devices, which are configured to stationarily receive the respective lateral screen at a respective frontal side of the door operator.
- the door operator has fastening devices, which are configured to stationarily receive the covering hood.
- fastening devices which are configured to stationarily receive the covering hood.
- the door operator exclusively retain the parts of the encasing, namely the lateral screen(s) and the covering hood, which makes installation easy in so far as the parts only need to be placed onto the door operator.
- the door drive has appropriate fastening devices and lateral screens for each frontal side.
- This feature allows for manufacturing covering hoods which are open towards both frontal sides.
- This feature also allows for manufacturing endless extruded parts having for example a C-shaped or U-shaped cross-section that matches the desired cross-sectional shape of the covering hood.
- the manufactured profile is then cut to length at the desired locations, which results in very simple and inexpensive manufacturing.
- no control elements need to be affixed to the newly created covering hoods, if it is not desired. Therefore, in order to access said control elements and/or display elements, it is furthermore advantageous that it is no longer required to remove the covering hood including the above elements with the risk of tearing off the electrical lines or the like.
- the lateral screen(s) and thus the control elements and/or the display elements remain preferably installed.
- the door operator has preferably, at least at one frontal side, a fastening device configured to stationarily receive an associated electronic component at a respective frontal side of the door drive.
- a fastening device configured to stationarily receive an associated electronic component at a respective frontal side of the door drive.
- Such components may include switches, display elements or the like, which are advantageously disposed on a printed circuit board. Uninstalling/installing the associated lateral screen is thus possible without having to remove the electronic component, in addition to the advantage of lowering the risk of damaging for example electrical lines, as already described in conjunction with the covering hood.
- each lateral screen advantageously comprises devices such as through-bores and the like, which allow for accessing or seeing the control and/or display elements, such as switches, LEDs, displays etc, from the outside with regard to the door drive. Therefore, it is no longer required to manipulate the covering hood, and it no longer needs to have such drive specific devices.
- At least one lateral screen has at least one through-bore, which, in the installed condition, extends along a longitudinal extension of the door drive and is aligned with a cooling air stream of the door drive in the area of this lateral screen.
- An air stream for cooling the door operator, respectively parts thereof, such as the power supply unit, electronic components, the control and the like, can thus be realized. This means neither in this case nor the covering hood needs to be machined.
- a mounting method for such a door drive includes a step of placing onto, respectively inserting at least one lateral screen into the associated fastening devices of the door drive and a step of placing the covering hood onto the door drive provided with the one or more lateral screens.
- the mounting method furthermore includes a step of fastening this electronic component to the associated frontal side of the door operator. This step is executed prior to installing the lateral screen to be installed at the same frontal side of the door operator.

- Warm air develops when operating such electric door drives 100 , i.e. motor-driven door drives.
- Heat development may occur in the door drive 100 , when a motor 101 of the door drive 100 , illustrated in FIG. 2 , is under load while opening, respectively closing the connected door leaf, respectively when the electrical components, such as the power supply units and the like, for supplying power and controlling, are under load. If the heat is not evacuated, the door drive 100 could overheat and be damaged.
- the same may obviously apply to potential other components such as a light curtain, radar alarm, or the like, which may be likewise covered by the covering hood 10 .
- the heat needs to be evacuated, by either convection or by active ventilators.

- the motor 101 has a drive shaft exiting at both sides.
- the end exiting on the left side is operatively coupled to a blocking device 102 , which may be a part of a non-illustrated closing sequence control.
- a system carrier 120 of the door drive 100 is located adjacent to the left side of the gear housing 103 .
- the system carrier 120 is adapted to stationarily receive or to retain additional driving components such as a power supply unit, a driving control, sensors, and the like.
- the lateral screen 20 and the switch member 30 are preferably affixed to the left frontal side of the system carrier 30 , namely at the side facing away from the gear housing 103 .
- FIG. 3 shows partial views of the door drive 100 of FIG. 1 , with regard to affixing the switch member 30 of FIG. 1 , respectively in an enlarged cut out.
- FIG. 3 a shows the door drive 100 in an arrangement of FIG. 1 without the covering hood 10 and mounting plate 1 .
- FIG. 3 b shows this arrangement in a section along a line A-A of FIG. 3 a in an essentially rear perspective, which differs from FIG. 3 a.
- the door drive 100 is equipped with an electronic component configured as a switch member 30 .
- the lateral screen 20 is disposed at this frontal side, in the shape of a perforated screen.
- the lateral screen 20 terminates the frontal side of the door drive 100 .
- the lateral screen 20 has the function of a terminal cap and, in the illustrated example, allows for disposing the switch member 30 , which by way of example, has two switches 31 , 32 .
- the lateral screen 20 has through-openings disposed in a matrix and form the aforementioned ventilating grille 21 .
- the ventilating grille 21 provides air flow into the inside chamber, between the non-illustrated covering hood 10 and through the driving components 101 to 103 , in this case indicated by way of example, or to evacuate warm air from this inside chamber to the outside.
- the air may likewise flow through these parts of the door drive 100 to cool additional components such as the power supply unit, the control, and the like.
- the switch member 30 comprises a printed circuit board 33 on which the switches 31 , 32 are disposed. Furthermore, a connecting cable 34 starts at the printed circuit board 34 and leads to a non-illustrated control device.
- the switch member 30 is inserted into the system carrier 120 from the top in FIG. 3 , preferably without any additional fastening elements. Thereafter, the lateral screen 20 is placed onto the system carrier 120 at the frontal side thereof.
- the system carrier 120 comprises a support surface 122 .
- the support surface 122 thus forms a support for the switch member 30 , respectively the printed circuit board 33 thereof.
- the switches 31 , 32 of the switch member 30 offer support in the system carrier 120 .
- the system carrier 120 preferably has latching projections 123 , which extend towards each other at the side of the switch member 30 .
- Each switch 31 , 32 has a plate-shaped part including a break-through for a respective electrical switch element 31 a, 32 a of the respective switch 31 , 32 .
- the switch elements 31 a, 32 a are configured as rocker switches.
- the plate-shaped parts serve as support portion 31 b, respectively 32 b.
- the switches 31 , 32 with their portions 31 b, 32 b, come to bear on the latching projections 123 from the outside with regard to the system carrier 120 .
- the installation procedure is as follows: Initially, the printed circuit board 33 of the switch is inserted from the top, namely in the ⁇ y coordinate direction in FIG. 3 c , into the system carrier 120 . Once the latching projections 123 are located between the clamping portions 31 c, 32 c and the printed circuit board 33 of the switch, the switches 31 , 32 are simply pushed as far towards the latching projections 123 , namely in the +x coordinate direction in FIG. 3 c , until the clamping portions 31 c, 32 c have overcome the latching projections 123 , and therefore latch therein and the switch member 30 has thus reached the position shown in FIG. 3 c.
- FIG. 4 shows partial views of the door drive 100 of FIG. 1 with regard to mounting the lateral screen 20 .
- FIG. 4 a is a sectional view through the system carrier 120 along a line, which is displaced a little bit in the direction of the lateral screen 20 and parallel to line A-A.

- the lateral screen 20 has fastening devices in the shape of projections 23 , 24 projecting in the direction of the system carrier 120 .
- they include a quadrangle with rounded corners.
- the projections 23 thus disposed in the corner areas of this quadrangle serve to push the lateral screen 20 onto the system carrier 120 in a guided manner.
- the thus configured push-on projections 23 are not straight, but angled, respectively as illustrated here and seen in the longitudinal direction of the system carrier 120 , they are configured to be concave and arched at the sides facing each other.
- the system carrier 120 has essentially complementary guiding portions 124 configured to be convex.
- a latching mechanism is provided.
- the arched shape of the projections 23 interferes with a flexible resiliency of the projections 23 . Therefore, they are rather not suited for a latching mechanism.
- the aforementioned projections 24 are provided, which in cross-section are configured to be flat and resilient.
- the latching projections 24 have latching noses 25 facing each other. When being inserted into the system carrier 120 , the latching noses 25 reach engagement with corresponding latching recesses of the system carrier 120 . In the illustrated example, these latching recesses are configured by respective latching groove portions 125 of the system carrier 120 .
- Each latching groove portion 125 has a plurality of latching grooves, which are not identified in detail, that extend parallel with regard to each other and essentially transversely to the insertion direction of the lateral screen 20 .

- one latching recess corresponding to the latching nose 25 may be configured, however linked to the disadvantage of the missing variable insertion depth.
- This positioning mechanism allows for an installation, which simply consists of inserting the lateral screen 20 into the system carrier 120 by pushing it on the latter.
- the portions 23 , 24 , 124 ensure that the above described switches 31 , 32 can pass through the associated through-openings 22 of the switch member 20 , and that, as already described above and by way of example, the ventilating grille 21 , for the cooling air stream, is aligned with the aeration opening, respectively through-opening 121 of the system carrier 120 .
- FIG. 4 c shows the system carrier 120 in the direction of the frontal face facing the non-illustrated lateral screen 20 .
- the system carrier 120 has two projections 126 , which extend in the direction of the lateral screen 20 and serve as an abutment, respectively as a contact surface for the non-illustrated lateral screen 20 . This means, the abutment projections 126 determine the maximum insertion depth of the lateral screen 20 with regard to the system carrier 120 .
- FIG. 5 shows the connecting module 110 of the door drive 100 in different views in conjunction with a lateral screen 40 .
- the lateral screen 40 closes the frontal face which is opposite to the one in FIG. 3 of the door drive 100 represented by the connecting module 110 .

Abstract
Description
- This is a U.S. national stage of application No. PCT/EP2009/008085, filed on 13 Nov. 2009.
- 1. Field of the Invention
- The invention relates to an encasing for a door drive adapted to open and/or to close a connected door leaf.
- 2. Description of Prior Art
- Door operators, namely door drives or door closers, are provided for actuating a door leaf of a door system. With pivotable doors, such door operators are installed most of the time at a top side at a door transom or a wall and are operatively connected to an associated door leaf via an arm assembly. There are door operators configured with an electro-motor or with electro-hydraulics. Such door drives for opening the door are typically activated by a momentary contact switch or a motion-sensor, and they execute both the opening procedure of the door leaf and the mostly time-delayed closing procedure. Furthermore, door operators are known which, for the purpose of controlling an escape route for example, are coupled to a bus of a building. Fully automatic door operators are very common in particular in public buildings, as well as in the infrastructure area of larger building complexes, which have a higher volume of people passing through.
- For the installation, the door operator has a mounting plate, stationarily affixed to a carrying body, namely a door transom, a wall, a casing, a door leaf or a door frame for example, by a screw-connection or any other known type of connection. Once the mounting plate is installed at the carrying body, the door operator itself is installed on the mounting plate. For mounting the door operator, the plate has, for example, pre-fabricated threaded bores or through-openings for screw-connections to firmly connect the door operator to said carrying body via the mounting plate.
- From the state-of-the-art encasings are known, that are realized by covering hoods which are simply open towards the mounting plate of such a door operator. This means, they encase the door drive towards all visible sides, respectively they cover the door drive to these sides. Such covering hoods are disadvantageous in that, for each type of door operator with a different length, different covering hoods need to be manufactured. In addition, appropriate devices are to be provided in the covering hoods such that control elements or display elements, such as switches or the like are accessible from outside.
- It is an object of the present invention to eliminate the above mentioned disadvantages.
- An inventive door operator is adapted to open and to close a connected door leaf. It is furthermore adapted to be stationarily affixed to a carrying body, such as a casing, a transom, a door leaf, or the like. The door operator has at least one lateral screen and a covering hood. In the installed condition, the covering hood is configured to be open towards the respective lateral screen. This means the at least one lateral screen, and not the covering hood, forms the frontal termination of the so-formed encasing for the door operator. According to the invention, the door operator has fastening devices, which are configured to stationarily receive the respective lateral screen at a respective frontal side of the door operator. In addition the door operator has fastening devices, which are configured to stationarily receive the covering hood. On the one hand, it is thereby possible to have the door operator exclusively retain the parts of the encasing, namely the lateral screen(s) and the covering hood, which makes installation easy in so far as the parts only need to be placed onto the door operator. Furthermore, it is still possible to completely cover the door operator towards the respective frontal side by means of associated lateral screen(s) and to the other sides by means of the covering hood, like a traditional covering hood would achieve on its own.
- Preferably the door drive has appropriate fastening devices and lateral screens for each frontal side. This feature allows for manufacturing covering hoods which are open towards both frontal sides. This feature also allows for manufacturing endless extruded parts having for example a C-shaped or U-shaped cross-section that matches the desired cross-sectional shape of the covering hood. The manufactured profile is then cut to length at the desired locations, which results in very simple and inexpensive manufacturing. In particular no control elements need to be affixed to the newly created covering hoods, if it is not desired. Therefore, in order to access said control elements and/or display elements, it is furthermore advantageous that it is no longer required to remove the covering hood including the above elements with the risk of tearing off the electrical lines or the like. With the covering hood being removed, the lateral screen(s) and thus the control elements and/or the display elements remain preferably installed.
- Furthermore, the door operator has preferably, at least at one frontal side, a fastening device configured to stationarily receive an associated electronic component at a respective frontal side of the door drive. Such components may include switches, display elements or the like, which are advantageously disposed on a printed circuit board. Uninstalling/installing the associated lateral screen is thus possible without having to remove the electronic component, in addition to the advantage of lowering the risk of damaging for example electrical lines, as already described in conjunction with the covering hood.
- In a preferred embodiment, each lateral screen advantageously comprises devices such as through-bores and the like, which allow for accessing or seeing the control and/or display elements, such as switches, LEDs, displays etc, from the outside with regard to the door drive. Therefore, it is no longer required to manipulate the covering hood, and it no longer needs to have such drive specific devices.
- As an alternative or in addition, at least one lateral screen has at least one through-bore, which, in the installed condition, extends along a longitudinal extension of the door drive and is aligned with a cooling air stream of the door drive in the area of this lateral screen. An air stream for cooling the door operator, respectively parts thereof, such as the power supply unit, electronic components, the control and the like, can thus be realized. This means neither in this case nor the covering hood needs to be machined.
- A mounting method for such a door drive includes a step of placing onto, respectively inserting at least one lateral screen into the associated fastening devices of the door drive and a step of placing the covering hood onto the door drive provided with the one or more lateral screens.
- If the door operator has in addition, as mentioned above, at least one electronic component to be frontally mounted, according to the invention, the mounting method furthermore includes a step of fastening this electronic component to the associated frontal side of the door operator. This step is executed prior to installing the lateral screen to be installed at the same frontal side of the door operator.
- Hereinafter, further measures enhancing the invention will be illustrated in detail in conjunction with the description of one preferred embodiment of the invention based on the Figures, in which:
-
FIG. 1 is a door drive according to an embodiment of the invention; -
FIG. 2 is the door drive ofFIG. 1 without covering hood and with a lateral screen modified compared toFIG. 1 ; -
FIGS. 3 a-3 c are partial views of the door drive ofFIG. 1 with regard to affixing the switch part ofFIG. 1 ; -
FIGS. 4 a-4 c are partial views ofFIG. 1 with regard to affixing the lateral screen ofFIG. 1 ; -
FIGS. 5 a-5 c are partial views of the door drive ofFIG. 1 , with regard to affixing a lateral screen to the frontal side of the door drive which is concealed inFIG. 1 ; -
FIG. 6 is the door drive ofFIG. 1 in an exploded view; -
FIG. 7 is a method for mounting the encasing for the door drive ofFIG. 1 according to a first embodiment of the invention; and -
FIG. 8 is a method for mounting the covering for the door drive ofFIG. 1 according to a second embodiment of the invention. -
FIG. 1 shows parts of adoor drive 100 according to an embodiment of the invention. This embodiment is configured for a door leaf which is independently actuated by adoor drive 100. For the sake of clarity, the driving components of thedoor drive 100 are not illustrated. - The
door drive 100 has a mountingplate 1, which, in a known way, is affixed to a likewise not illustrated carrying body, such as a door casing, a door transom, a door leaf, or the like. - A covering
hood 10 is “put over” the mountingplate 1 so the latter is concealed to the outside. InFIG. 1 at least at the side pointing downwards, namely in −z coordinate direction, preferably however also at the opposite non-visible side, namely pointing into the +z coordinate direction, the coveringhood 10 has a respective recess, oropening 11, which serves to expose the respective end of an output shaft of the door drive 100 so it can be coupled in a known manner to a driving linkage system. - In
FIG. 1 , alateral screen 20, by way of example in the shape of a perforated screen, is disposed at the left side, which screen frontally terminates the entire covering, respectively the coveringhood 10 and therefore frontally encases, respectively covers thedoor drive 100. This means thelateral screen 20 has the function of a terminal cap and, in the illustrated example, allows for disposing aswitch member 30, by way of example having twoswitches switches lateral screen 20 has matrix-like disposed through-openings that form a ventilatinggrille 21. - The ventilating
grille 21 serves the purpose of letting air flow into the inside between the coveringhood 10 and the mountingplate 1 or of evacuating warm air from theinside covering hood 10 to the outside. Warm air develops when operating such electric door drives 100, i.e. motor-driven door drives. Heat development may occur in thedoor drive 100, when amotor 101 of thedoor drive 100, illustrated inFIG. 2 , is under load while opening, respectively closing the connected door leaf, respectively when the electrical components, such as the power supply units and the like, for supplying power and controlling, are under load. If the heat is not evacuated, thedoor drive 100 could overheat and be damaged. The same may obviously apply to potential other components such as a light curtain, radar alarm, or the like, which may be likewise covered by the coveringhood 10. In order to prevent damage, the heat needs to be evacuated, by either convection or by active ventilators. In order to guarantee ventilation, cold air needs to be supplied to at least one location from the outside to said inside and, at least at one other location, it needs to be evacuated from said inside to the outside. - If a frontal side or the
lateral screen 20 thereof is disposed to have a minimum distance to a neighbouring wall, so the air can flow unhindered into one frontal side of thearrangement 20 and flow out of the other frontal side, the solution embodied by theaforementioned ventilation grille 21 is suggested. Alateral screen 40, which will be explained later in detail, is disposed at the right concealed end inFIG. 1 , which, with respect to the air flow, is configured similarly to thelateral screen 20. Thereby air flow is realized. -
FIG. 2 shows the door drive 100 ofFIG. 1 without the coveringhood 10, but with alateral screen 20, which is modified compared toFIG. 1 . In this case the ventilatinggrille 21 is omitted. As driving components, thedoor drive 100 has the above mentionedmotor 101, the non-visible driving shaft thereof, to the right side inFIG. 2 , being operatively coupled to a gear, which is received in ahousing 103. InFIG. 2 , in the right terminal area of thegear housing 103, a connectingmodule 110 is attached to the latter. - The connecting
module 110 mainly serves to electrically couple thedoor drive 100 to an external power supply and has appropriate electrical connections not illustrated in detail. - By way of example, the
motor 101 has a drive shaft exiting at both sides. The end exiting on the left side is operatively coupled to ablocking device 102, which may be a part of a non-illustrated closing sequence control. - A
system carrier 120 of thedoor drive 100 is located adjacent to the left side of thegear housing 103. Preferably thesystem carrier 120 is adapted to stationarily receive or to retain additional driving components such as a power supply unit, a driving control, sensors, and the like. - The
lateral screen 20 and theswitch member 30, as will be explained below, are preferably affixed to the left frontal side of thesystem carrier 30, namely at the side facing away from thegear housing 103. -
FIG. 3 shows partial views of the door drive 100 ofFIG. 1 , with regard to affixing theswitch member 30 ofFIG. 1 , respectively in an enlarged cut out. In this case,FIG. 3 a shows thedoor drive 100 in an arrangement ofFIG. 1 without the coveringhood 10 and mountingplate 1.FIG. 3 b shows this arrangement in a section along a line A-A ofFIG. 3 a in an essentially rear perspective, which differs fromFIG. 3 a. - As shown in
FIG. 3 a, by way of example at its left frontal side, thedoor drive 100 is equipped with an electronic component configured as aswitch member 30. Furthermore, thelateral screen 20 is disposed at this frontal side, in the shape of a perforated screen. Thelateral screen 20 terminates the frontal side of thedoor drive 100. This means thelateral screen 20 has the function of a terminal cap and, in the illustrated example, allows for disposing theswitch member 30, which by way of example, has twoswitches switches lateral screen 20 has through-openings disposed in a matrix and form theaforementioned ventilating grille 21. - As indicated above, the ventilating
grille 21 provides air flow into the inside chamber, between thenon-illustrated covering hood 10 and through the drivingcomponents 101 to 103, in this case indicated by way of example, or to evacuate warm air from this inside chamber to the outside. With regard to thesystem carrier 120 and the connectingmodule 110, the air may likewise flow through these parts of thedoor drive 100 to cool additional components such as the power supply unit, the control, and the like. - By way of example, the
switch member 30 comprises a printedcircuit board 33 on which theswitches cable 34 starts at the printedcircuit board 34 and leads to a non-illustrated control device. During installation, theswitch member 30 is inserted into thesystem carrier 120 from the top inFIG. 3 , preferably without any additional fastening elements. Thereafter, thelateral screen 20 is placed onto thesystem carrier 120 at the frontal side thereof. - By way of example, the
system carrier 120 comprises asupport surface 122. Thesupport surface 122 thus forms a support for theswitch member 30, respectively the printedcircuit board 33 thereof. - Preferably the
switches switch member 30 offer support in thesystem carrier 120. As shown inFIG. 3 c, thesystem carrier 120 preferably has latchingprojections 123, which extend towards each other at the side of theswitch member 30. Eachswitch electrical switch element respective switch switch elements support portion 31 b, respectively 32 b. Theswitches portions projections 123 from the outside with regard to thesystem carrier 120. Towards the printedcircuit board 33 of the switch, preferably resiliently configured clampingportions switches projection 123, are adjacent to theportions support portions projections 123, so theswitches entire switch member 30 is held in position. - The installation procedure is as follows: Initially, the printed
circuit board 33 of the switch is inserted from the top, namely in the −y coordinate direction inFIG. 3 c, into thesystem carrier 120. Once the latchingprojections 123 are located between the clampingportions circuit board 33 of the switch, theswitches projections 123, namely in the +x coordinate direction inFIG. 3 c, until the clampingportions projections 123, and therefore latch therein and theswitch member 30 has thus reached the position shown inFIG. 3 c. -
FIG. 4 shows partial views of the door drive 100 ofFIG. 1 with regard to mounting thelateral screen 20. In this case,FIG. 4 a is a sectional view through thesystem carrier 120 along a line, which is displaced a little bit in the direction of thelateral screen 20 and parallel to line A-A. Thelateral screen 20 has through-openings, respectively switchopenings 22 for theswitches - In order to have air circulate from the
lateral screen 20, respectively the ventilatinggrille 21 thereof to the parts of thedoor drive 100, respectively in opposite direction, thesystem carrier 120 has a through-opening 121, which, in the installed condition, is aligned with a cooling air flow passing through the ventilatinggrille 21. - At the side facing the
system carrier 120, thelateral screen 20 has fastening devices in the shape ofprojections system carrier 120. By way of example, they include a quadrangle with rounded corners. Theprojections 23 thus disposed in the corner areas of this quadrangle serve to push thelateral screen 20 onto thesystem carrier 120 in a guided manner. In cross-section, the thus configured push-onprojections 23 are not straight, but angled, respectively as illustrated here and seen in the longitudinal direction of thesystem carrier 120, they are configured to be concave and arched at the sides facing each other. At corresponding locations, thesystem carrier 120 has essentiallycomplementary guiding portions 124 configured to be convex. Thus, thelateral screen 20 is already pre-positioned when being pushed-on, respectively when being inserted into thesystem carrier 120, just the insert depth is not determined yet. - To fix the insert depth of the
lateral screen 20, a latching mechanism is provided. The arched shape of theprojections 23 interferes with a flexible resiliency of theprojections 23. Therefore, they are rather not suited for a latching mechanism. This is why, in addition, theaforementioned projections 24 are provided, which in cross-section are configured to be flat and resilient. At their free ends, by way of example the latchingprojections 24 have latchingnoses 25 facing each other. When being inserted into thesystem carrier 120, the latchingnoses 25 reach engagement with corresponding latching recesses of thesystem carrier 120. In the illustrated example, these latching recesses are configured by respectivelatching groove portions 125 of thesystem carrier 120. Each latchinggroove portion 125 has a plurality of latching grooves, which are not identified in detail, that extend parallel with regard to each other and essentially transversely to the insertion direction of thelateral screen 20. InFIG. 4 b, the insertion direction is suggested by a block arrow. It is thereby possible, depending on the respective conditions, to be able to vary the insertion depth of thelateral screen 20. -
FIG. 4 a shows the latching engagement of the latchingnoses 25 in a respective latching groove, in this case of avisible portion 125.FIG. 4 b shows the disposition prior to installing thelateral screen 20 along the block arrow. - Obviously, instead of several latching grooves, respectively one latching recess corresponding to the latching
nose 25 may be configured, however linked to the disadvantage of the missing variable insertion depth. - This positioning mechanism allows for an installation, which simply consists of inserting the
lateral screen 20 into thesystem carrier 120 by pushing it on the latter. Theportions openings 22 of theswitch member 20, and that, as already described above and by way of example, the ventilatinggrille 21, for the cooling air stream, is aligned with the aeration opening, respectively through-opening 121 of thesystem carrier 120. -
FIG. 4 c shows thesystem carrier 120 in the direction of the frontal face facing thenon-illustrated lateral screen 20. Furthermore, as can be seen, thesystem carrier 120 has twoprojections 126, which extend in the direction of thelateral screen 20 and serve as an abutment, respectively as a contact surface for thenon-illustrated lateral screen 20. This means, theabutment projections 126 determine the maximum insertion depth of thelateral screen 20 with regard to thesystem carrier 120. -
FIG. 5 shows the connectingmodule 110 of thedoor drive 100 in different views in conjunction with alateral screen 40. In this case, thelateral screen 40 closes the frontal face which is opposite to the one inFIG. 3 of the door drive 100 represented by the connectingmodule 110. An exemplary ON-OFF switch 2 for the door drive 100 passes through thelateral screen 40, similarly to thelateral screen 20. Preferably, thelateral screen 40 is latched to the connectingmodule 110. By way of example, this is done by two tongues as thefastening projections 43, only one being visible inFIG. 5 a. By means of a latchingrecess 44, eachfastening projection 43 latches with an associated latchingnose 111 configured at the connectingmodule 110. -
FIG. 5 b shows the disposition ofFIG. 5 a from another perspective and prior to installing thelateral screen 40 onto the connectingmodule 110 in the direction of the block arrow. In this case, the twofastening projections 43, in the shape of a respective latching tongue, with arespective latching recess 44 located inside, are visible. Furthermore, preferably anadditional fastening projection 45 with a latchingnose 46 is provided at the free end of thefastening projection 45. In the illustrated example, the latchingnose 46 is configured so that the latching projection thereof (not indicated) points upwards inFIG. 5 b. In the installed condition, the latchingnose 46 engages behind an associated latchingsurface 112 of the connectingmodule 110. Thereby, thelateral screen 40 is kept in the installed position by three latchingmechanisms lateral screen 40 has a through-opening 41 which serves for the above indicatedswitch 2 to pass therethrough. Furthermore, preferably thelateral screen 40 hasinsert projections 42, which protrude in the direction of the connectingmodule 110. They engage, as can be seen inFIG. 5 c, in correspondinginsert openings 113 of the connectingmodule 110. Thefastening projections lateral screen 40 at the connectingmodule 110. In addition, a latchingnose 46, a latchingprojection 43 with latchingopening 44, as well as the latchingnose 46 with associated latchingsurface 112 can be seen. - Preferably the
lateral screen 40 has moreover pre-punched break-awayareas 47, for example to possibly pass external power supply lines through the broken-awayareas 47 of thelateral screen 40. -
FIG. 6 shows thesystem carrier 120, the connectingmodule 110 and the coveringhood 10 in an exploded view. In order to fasten the coveringhood 10, at surfaces, facing each other, of its non-identified lateral legs, the hood has groove-shapedrecesses 12, which preferably extend over the entire length of the covering hood. When placing the hood along the block arrow, therecesses 12 reach a latching engagement withcorresponding projections system carrier 120, respectively of the connectingmodule 110, what represents a very simple mounting of the coveringhood 10. Instead ofseveral latching projections latching projection -
FIG. 7 shows an installation method for the encasing, comprising the lateral screen(s) 20, 40 and of the coveringhood 10. After starting with step S1, if electronic components (for example the switch member 30) in conjunction with one of the lateral screens 20, 40 are to be mounted (branch YES following step S2), in a subsequent step S3 the respective component is placed onto the respective fastening device(s) 122, 123 of the door drive 100 or they are inserted into the device(s). Thereupon, or if no more electronic components are to be installed (branch NO following step S2), in a following step S4, the one or morelateral screens hood 10 is placed onto thedoor drive 100, or better onto thefastening devices hood 10, in an additional step, not-illustrated in this case, it may be provided to move theselateral screens hood 10. Thereupon the installation is finished in a step S6. -
FIG. 8 shows an installation method which, compared toFIG. 7 , is modified. Unlike in the previous embodiment, the steps S4 and S5 are interchanged. This means the coveringhood 10 is mounted prior to mounting the lateral screens 20, 40. This is advantageous in that the lateral screens 20, 40 can be correctly installed with regard to their insert depth when putting them in place, because the coveringhood 10 is already installed. - The invention in its configuration is not limited to the above described embodiments.
- The
fastening devices 23 to 25; 42 to 46 of the lateral screens 20, 40 may be interchanged or they may be combined with each other. In this case, thesystem carrier 120 and the connectingmodule 110 are correspondingly configured. - Instead of the
system carrier 120 and of the connectingmodule 110, other parts as well, such as thegear housing 103, may be configured to stationarily receive one of the respective lateral screens 20, 40. - The latching recesses 12 and the corresponding latching
projections gear housing 103. - The
door drive 100 may be replaced by any type of door drive or door closer, as long as it includes fastening devices for lateral screens. - The above described installation method may be modified in so far that in case of two
lateral screens lateral screen lateral screen other lateral screen second lateral screen - The through-openings of the above described ventilating
grille 21 may be likewise used to make switches or display elements accessible, respectively visible from the outside. - As a result, the invention provides a simple and installation-friendly covering, respectively a facing for a door operator.
